Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675878, here are decompositions:

17 + 8675861 = 8675878
179 + 8675699 = 8675878
227 + 8675651 = 8675878
257 + 8675621 = 8675878
479 + 8675399 = 8675878
521 + 8675357 = 8675878
569 + 8675309 = 8675878
857 + 8675021 = 8675878

Showing the first eight; more decompositions exist.
